I like the idea of being able to keep your melee weapon out, there are those times in WFC where if you could even do a 2 hit combo you would get that kill especially when you catch an enemy mid transformation.

I would like the usual melee combo , where you press the button three times and it does a combo move ,
or off batman Arkam city, all the fight moves are seamlessly one after the other with no indication of the end of a certain move
That would be awesome!

I think having a melee system where there are more than just 4 types of weapons would be cool. It could use your system, where holding the button would cause the weapon to deploy, but also, the ability button would change to a melee ability button. Each ability is different for each weapon. These abilities take a long time to recharge due to their power.

Soldiers:
Broadsword: Power slash. Slash the opponent with a heavy, overhand swing. Slow attack.
Mace: Power shock. The impact sends the opponent flying backwards. Deals damage with impact and any wall hit.
Hammer: Ground pound. Especially effective from the air.
Chainsaw: Super rev. Fuel the chainsaw with a powerful energy, and slice down enemies with major efficiency.

Scientist:
Spear: Throw. Throw the spear at an enemy. Must pick up to use again.
Scythe: Super sweep: Sweep the ground in a massive swing to take down multiple opponents.
Trident: Dash stab. Dash forward to impale opponent.
Chain knife: Grapple. Drag in opponent.
